# Information Needed for Documentation

This document outlines the information needed to complete the home automation system documentation. Please provide as much detail as possible for each section.

## 1. Network Configuration

- [ ] IP addresses for all devices:
  - Raspberry Pi (CODESYS)
  - Node-RED host
  - MQTT broker (LXC container)
  - Zigbee2MQTT host
  - Home Assistant host
- [ ] Network topology (VLANs, subnets, etc.)
- [ ] Port numbers used by services (MQTT, Node-RED, Home Assistant, etc.)
- [ ] Firewall rules or network restrictions

## 2. CODESYS Configuration

- [ ] CODESYS version and license type
- [ ] Network variable names and types (sent to Node-RED)
- [ ] Network variable names and types (received from Node-RED)
- [ ] EtherCAT IO card model and configuration
- [ ] Relay mapping (which relay controls which light/device)
- [ ] Water boiler control logic
- [ ] Project file location or export (if available)

## 3. Node-RED Configuration

- [ ] Node-RED version
- [ ] Flow export or description of main flows
- [ ] MQTT topics used for communication
- [ ] CODESYS network variable integration details
- [ ] Custom nodes or functions used
- [ ] Automation logic descriptions

## 4. MQTT Broker

- [ ] MQTT broker software (Mosquitto, Eclipse, etc.) and version
- [ ] LXC container specifications
- [ ] Authentication configuration (users, passwords, ACLs)
- [ ] Topic structure and naming conventions
- [ ] Retain policies and QoS levels

## 5. Zigbee2MQTT

- [ ] Zigbee2MQTT version
- [ ] Coordinator device model
- [ ] List of Zigbee devices (switches, sensors, etc.) with:
  - Device names
  - Model numbers
  - MQTT topics
  - Functions/features
- [ ] Configuration file location or export
- [ ] Network key (if you're comfortable sharing, or note that it's stored securely)

## 6. Home Assistant

- [ ] Home Assistant version and installation type (HassOS, Docker, etc.)
- [ ] Integration configurations:
  - MQTT integration settings
  - Node-RED integration (if used)
  - Zigbee integration (if direct)
- [ ] Dashboard screenshots or descriptions
- [ ] Automation rules
- [ ] Custom components or add-ons

## 7. Hardware Inventory

- [ ] Raspberry Pi model and specifications
- [ ] Beckhoff EtherCAT IO card model number
- [ ] Relay module details (model, number of channels)
- [ ] Zigbee coordinator hardware
- [ ] Zigbee switch models and quantities
- [ ] Water boiler model and control interface
- [ ] Any other connected hardware

## 8. Physical Wiring

- [ ] Relay to device mapping (which relay controls which physical device)
- [ ] Wiring diagrams or descriptions
- [ ] Safety considerations or warnings

## 9. Automation Logic

- [ ] How light switches trigger actions
- [ ] Water boiler control logic and schedules
- [ ] Any time-based automations
- [ ] Error handling and fallback behaviors
- [ ] Manual override procedures

## 10. Access Information (Optional)

If you'd like me to access services directly to gather information:

- [ ] SSH access details (if comfortable)
- [ ] Web interface URLs and credentials (if comfortable)
- [ ] API endpoints and authentication
- [ ] File system paths to configuration files

**Note:** Only provide access information if you're comfortable doing so. I can work with exported configuration files instead.

## 11. Troubleshooting & Known Issues

- [ ] Common problems and solutions
- [ ] Known limitations
- [ ] Planned improvements

## Priority Items

To get started quickly, the most important information is:
1. Network IP addresses and topology
2. CODESYS network variable names
3. MQTT topic structure
4. Zigbee device list
5. Relay to device mapping

---

**How to Provide Information:**

1. Fill out this checklist and provide details in a separate document
2. Export configuration files and share them
3. Grant access to services (if comfortable)
4. Provide screenshots of configurations
5. Schedule a walkthrough session

Let me know your preferred method!
